Enumerations
enum	CommandId {   MoveSelectionId , ResizeWorkspaceId , WidgetGeometryId , RotateAnchorId ,   ChangeOperationColorId }

Detailed Description

The commands within this namespace should actually endeavour to only require things from the DataExecution namespace and not from the Presentation namespace. This will allow the commands to be used when there is no WorkspaceView available for a given Workspace. This is particularly relevant for commands that a WorkspaceView, OperationView, etc. responds to because the commands must remain undoable/redoable after the user closes all views associated with the objects being altered by the commands. For an example of how this can be achieved for some of the more complicated situations, see the MoveSelection class.

Enumeration Type Documentation

CommandId

enum CommandId

All QUndoCommand subclasses to be used with a WorkspaceView and which override the QUndoCommand::id() function must put an entry in this enum and use it as the return value. This ensures that no two subclasses use the same id unintentionally. The recommended name of the entry is the class name with "Id" appended.

Note that these should never become visible to any code except the Workspace module. WorkspaceView commands should all be private.
